Connect CDC SQData

The IMS Log Reader Capture supports the capture of changed IMS data from the both batch and on-line recovery logs made by IMS transactions (MPP), Fast Path transactions (FPP), CICS/DBCTL transactions, batch message programs (BMP) and DL/I Batch programs. The Log Reader Capture Agent (SQDIMSC) extracts only the committed changed IMS data from recovery log(s) and writes them to a z/OS System LogStream. The zLog Publisher component then manages the captured data by communicating with downstream Engines via TCP/IP. Once an individual Unit-of-Work has been forwarded to all target Engines and consumed, the CDCzLog Publisher deletes the data from the LogStream.

Note:  This capture method requires enhanced logging which generates IMS Recovery log "99" records for third party tools, such as Connect CDC SQData, to gain access to changed data.
